Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT BELT PRE-TENSIONER” EKS001SS

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used alongwith a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certaintypes of collision. Information necessary to service the system safely is included in the SRS and SB section ofthis Service Manual.WARNING: To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death

in the event of a collision which would result in air bag inflation, all maintenance must be per-formed by an authorized NISSAN/INFINITI dealer.

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and AirBag Module, see the SRS section.

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in thisService Manual. SRS wiring harnesses can be identified by yellow and/or orange harness connec-tors.

[LAN]IVMS (LAN)

IVMS (LAN) PFP:28491

Overall Description EKS001ST

OUTLINEThe In-Vehicle Multiplexing System, IVMS (LAN system), consists of a BCM (Body Control Module) and fourLCUs (Local Control Units). Some switches and electrical loads are connected to each LCU. Some electricalsystems are directly connected to the BCM. Control of each LCU, (which is provided by a switch and electricalload), is accomplished by the BCM, via multiplex data lines (A-1, A-2 or A-3) connected between them.

BCM (BODY CONTROL MODULE)The BCM, which is a master unit of the IVMS (LAN), consists of microprocessor, memory and communicationLSI sections and has communication and control functions. It receives data signals from the LCUs and sendselectrical load data signals to them.

LCU (LOCAL CONTROL UNIT)The LCUs, which are slave units of the BCM, have only a communication function and consist of communica-tion LSI and input-output interface circuits. They receive data signals from the BCM, control the ON/OFF oper-ations of electrical loads and the sleep operation, as well as send switch signals to the BCM.

CONTROLLED SYSTEMSThe IVMS controls several body-electrical systems. The systems included in the IVMS are as follows: Power window system (Refer to GW-9, "POWER WINDOW SYSTEM" ) Power door lock system (Refer to BL-21, "POWER DOOR LOCK SYSTEM" ) Remote keyless entry system (Refer to BL-79, "REMOTE KEYLESS ENTRY SYSTEM" ) Theft warning system (Refer to BL-194, "THEFT WARNING SYSTEM" ) Reverse interlock door mirror system (Refer to GW-109, "REVERSE INTERLOCK DOOR MIRROR SYS-

TEM" ) Interior room lamp (Refer to LT-70, "INTERIOR ROOM LAMP" ) Step lamp (Refer to LT-104, "STEP LAMP" ) Illumination (Refer to LT-135, "ILLUMINATION" ) Automatic drive positioner (Refer to SE-5, "AUTOMATIC DRIVE POSITIONER" ) Auto light (Refer to LT-5, "HEADLAMP" ) Door warning lamp (Refer to DI-28, "WARNING LAMPS" ) Ignition key warning (Refer to DI-60, "WARNING CHIME" ) Light warning (Refer to DI-60, "WARNING CHIME" ) Front wiper and washer system (Refer to WW-4, "FRONT WIPER AND WASHER SYSTEM" ) Rear window defogger timer (Refer to GW-77, "REAR WINDOW DEFOGGER" ) Trouble diagnosis system

—with CONSULT-II—ON BOARD

Also, IVMS has the “sleep/wake-up control” function. IVMS puts itself (the whole IVMS system) to sleep undercertain conditions to prevent unnecessary power consumption. Then, when a certain input is detected, thesystem wakes itself up. For more detailed information, refer to “Sleep/Wake-up Control”.

SLEEP CONTROL

“Sleep” control prevents unnecessary power consumption. After the following conditions are met, the BCMsuspends the communication between itself and all LCUs. The whole IVMS is set in the “sleep” mode. Ignition switch “OFF” All electrical loads (in the IVMS) “OFF” Timer “OFF”

WAKE-UP CONTROL

As shown above, when the BCM detects a “wake-up” signal, it wakes up the whole system and starts commu-nicating again. The “sleep” mode of all LCUs is now canceled, and the BCM returns to the normal controlmode. When any one of the following switches are turned ON, the “sleep” mode is canceled: All switches combined or connected with BCM All switches combined or connected with LCU

Fail-safe System EKS001SW

Fail-safe system operates when the signal from LCU is judged to be malfunctioning by BCM. If LCU sends nosignal or an irregular signal to BCM a certain number of times in succession, the IVMS is set in a fail-safe con-dition. In the fail-safe condition, the electrical loads controlled by the switch on the questionable LCU will beoperated at fail-safe mode.

CONSULT–II Function EKS001SX

CONSULT-II executes the following functions by combining data reception and command transmission via thecommunication line from BCM. IVMS communication inspection, work support (only function setting of seatsand steering wheel), self-diagnosis, data monitor, and active test display.

Precautions For Harness Repair EKS001T8

CAN SYSTEM Solder the repaired parts, and wrap with tape. [Frays of twisted

line must be within 110 mm (4.33 in)]

Do not perform bypass wire connections for the repair parts.(The spliced wire will become separated and the characteristicsof twisted line will be lost.)

CAN COMMUNICATION PFP:23710

System Description EKS001T9

CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-tiplex communication line with high data communication speed and excellent error detection ability. Many elec-tronic control units are equipped onto a vehicle, and each control unit shares information and links with othercontrol units during operation (not independent). In CAN communication, control units are connected with 2communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.Each control unit transmits/receives data but selectively reads required data only.
